CAIRO (AP) — A gunman on a motorcycle opened fire Friday outside a church in a Cairo suburb and at a nearby store, sparking a shootout that killed at least nine people, including eight Coptic Christians, authorities said. It was the latest attack targeting Egypt’s embattled Christian minority.

The gunman was also killed, along with at least one police officer, officials said.

The local affiliate of the extremist Islamic State group claimed responsibility for the attack late Friday, saying it was carried out by a “security detail” and that one of its men was “martyred” in the strike. The claim was carried by the group’s Aamaq news agency.

The attack began when the gunman tried to break through the security cordon outside the Coptic Church of Mar Mina. It was not clear how many assailants were involved. Egypt’s Interior Ministry referred to only one, but the Coptic Orthodox church mentioned “gunmen.”

Five people were wounded, including another police officer, Health Ministry spokesman Khaled Megahed said.
